Some years ago Andrea Centazzo was invited by long time friend trombonist Giancarlo Schiaffini to play in a trio with vibraphonist Sergi Armaroli. The trio, named "Trisaghion", recorded a CD in 2017 followed by occasional concerts. In June 2919 while in Berlin to present "The Seer", one of his multimedia solos, AC was approached by Harri Sj"str"m for a trio gig with bassist Matthias Bauer. The music went very well. This led to the next natural step to add Harri to the trio and form the quartet on this CD. The title comes from the tracks organized in a way that a player starts improvising and the others join one by one until the cycle or "orbit" is completed. The quartet is a solid combination of 2 percussion sets, including AC electronics and 2 wind players covering a wide range of sounds. At this point the methodology of free improvisation has become an international language and this quartet speaks the language fluently. Welcome to "Orbits"
